IMPROVENI ENT IN GASREGULATORS.V

Specification forming part of Letters Patent No.V 35,538, dated June 10, 1862.

` l ac't description, reference being had to the accompanyingl drawings, making part of this specification, in which- Figure 1 is a vertical section through the middle of my improved regulatorg Fig. 2, a perspective view of the upper part of the box or shell, the lowerchamber being removed.

`In the construction of gas-regulators. I have found in practicethat whenever the now of the gas through the inlet-pipe is checked either by an elbow or a sudden `bend in the pipe, or

O H by any body Oo`f` metalplaced opposite to and O nearth'e mouth of the pipe, that a deposit of tar from the gas is.` the result.

`I he object of my present invention is to avoid this checking of the flow of the gas and this consequent deposit, and also to avoid the use of levers and pivots with which the gas may come in contact and, by depositing its im# purities on them, obstruct their operation; and my invention consists substantiallyin the following construction and arrangement of parts, which, as a whole, constitute `my improved regulator. y l

That others skilledin the art may understand-and use my-invention, I. will proceed to describe the manner in which I` have carried out the same. O

In the said drawings, A is a circular bowl O of `cast iron,withan outlet at B where the service-pipe isattached. `It has a trough around its edge, which is partially filled with quicksilver, as shown at a, Fig. 1, in which the edge of an inverted cup, C, of sheet metal, is placed 'to prevent the escape of gas from the chamber D, thus formed, except through the outlet B.

y A cover,E, ofcastiron, is secured by screws b to the edge of the part A to protect the cup C,

`formed a series of notches, 12 3 4, of varying depth, a central hole, ge, opening through the bottom into the chamber D. Two rods, g,with screws on their ends, are also attached to the bottom d. Y

A second part or bowl, F, is connected with the first one. The bottom edgeof the part A rests within a rim, h, and the rods g pass through holes in the bottom of the part F, the

`two being drawn up tight together by nuts i.

The holes around the rods, and also the joint around inside of the rim lz., are rendered gastight by cement, in the usual manner. The I chamber'1 G in the part F has an inlet, H, through which gas is admitted. A vertical pipe, I, at the bottom of the part F,with a screw-cap` k, on its end,serves for the collection and removal of any deposit from the gas.

A rod, L, is suspended by two screw-nuts, fm, m2, from the center of the cup G, It has at-O tached to its lower end a cup, M, filled with quicksilver. By adjusting the nuts m m2 this cup is broughtinto the proper position corresponding with the greatest number of burners to be supplied by the service-pipe B, or wi th the greatest probable pressure to be maiutained in the chamber D, so that theproper O amount of opening through the notches 1 2 8 4 kmaybe provided to supply the amount of gas required by the number of burners in use at any one time. O

The following is the operation of the apparatus. rlhe gas enters at the inlet H into the chamber G, and, asindicated by the arrows, passes over the edge of the cup M and through so much of the openings 1 2 3 4 of the cylinder f as may be exposed above the quicksilver -in the cup M, through the passage e into the chamber D, where itsV pressure tends to raise the cup C.' As the pressure in this chamber D is increased by shutting off the burners supplied by the pipe B, the cup M will be raised and a larger portion of the openings 1 2 3 4 in the cylinder f will be closed. The rise and `fall ofthe inverted cup O is thnscommunicated directly to the cup M wit-hout the intervention of levers orpivots, and there is no part of the regulator that'is liable to be clogged by deposits from the gas. At the same time the cost of its construction is, less than i that of any other regulator with which I am acquainted. I am aware of the patent granted to John H. Powers September l, 1857, for improvements iu gus-regulators. I do not, therefore, claim to be the irst to use a eup or trough of quieksilvei us a.. seat for the vulve which regulates the flow of gus into the pressurevehumber I).

I am also aware that a cup of Quicksilver suspended from the Hout has been used to close, more or less, the mouth of a bent inlet pipe to regulate the flow of gas into a, pressureehumber like the chamber D; but in such regu` letors the current or stream of gas flowing through the iuletpipe received a cheek by the short turn ofthe pipe, und also by its striking ou the body of Quicksilver in the cup, and u deposit in the pipe und @up was the consequence. This difficulty I have entirely overcome by admitting the gas from the inlet-pipe H into at chamber, G, from which it flows valvef into the pressure-chamber D.

1What I claim es my invention, and desire to secure by Letters Patent, is-

The chamber G, into which the gas is poured from the inletpipe H, iu combination with the valve f, communicating with the pressurechamber D when said valve is commanded by the quieksilvereup M, suspended directly from the inverted ou p C, substantially as speeill. H. NORTON.
